angular - How to get first objects of an Observable -


i have observable contains list of users, , want take part of it, handle pagination. how can that? i've tried filter doesn't workk :

this.users.filter(function (x: any, idx: number) {   return idx < 3; });

just use array slice inside of map operator. depending on page , page size can set so:

const pageindex = 0; const pagesize = 3; this.users.map((users: user[]) => {     return users.slice(pageindex, pagesize); });
